Questions and Answers

What is the goal of a non-inferiority trial?

  • To demonstrate that the new intervention is significantly better than the control
  • To demonstrate that the new intervention is superior to the control
  • To demonstrate that the new intervention is equivalent to the control
  • To demonstrate that the new intervention is not worse than the standard by a predefined margin (correct)

What is the objective of a study of equivalency?

  • To test whether a new intervention is superior to an established one
  • To test whether a new intervention is no worse than an established one
  • To test whether a new intervention is equivalent to an established one (correct)
  • To test whether a new intervention is significantly better than an established one

What is the assumption about the active control in non-inferiority trials?

  • It must be equivalent to the new intervention
  • It must be superior to the new intervention
  • It must be one that the new intervention is not worse than by a predefined margin (correct)
  • It must be significantly better than the new intervention

What are some reasons why a new intervention may be of interest in non-inferiority trials?

What is the difference between studies of equivalency and studies of non-inferiority?

<p>Studies of equivalency test whether a new intervention is equivalent to an established one, while studies of non-inferiority test whether the new intervention is no worse than an established one (A)</p> Signup and view all the answers

What is the primary goal of a non-inferiority trial and how does it differ from a superiority trial?

<p>The primary goal of a non-inferiority trial is to demonstrate that the new intervention is not worse than the standard by a predefined margin. This differs from a superiority trial, which aims to show that the new intervention is better than the control, without specifying a margin of non-inferiority.</p> Signup and view all the answers

What are some potential reasons why a new intervention may be of interest in non-inferiority trials?

<p>A new intervention may be of interest in non-inferiority trials because it is less toxic, less invasive, less costly, requires fewer doses, improves quality of life, or provides other value to patients, even if it does not demonstrate superiority over existing therapies.</p> Signup and view all the answers

What are the key objectives of studies of equivalency and studies of non-inferiority?

<p>The key objective of studies of equivalency is to test whether a new intervention is equivalent to an established one, while the objective of studies of non-inferiority is to test whether the new intervention is no worse than, or at least as good as, some established intervention.</p> Signup and view all the answers

What are the assumptions regarding the selection of active control in non-inferiority trials?

<p>The active control selected in non-inferiority trials must be one that is a well-established treatment for the condition being studied and has been shown to be effective in previous trials.</p> Signup and view all the answers

What is the significance of demonstrating non-inferiority in a clinical trial?

<p>Demonstrating non-inferiority in a clinical trial is significant because it provides evidence that the new intervention is at least as good as the standard treatment, which can be valuable in cases where the new intervention offers other benefits such as reduced toxicity, invasiveness, or cost.</p> Signup and view all the answers
